What do the Gallic Wars and online shopping have in common? The answer, believe it or not, is cryptography. Cryptography is the cement of the digital world, but it also has a long history that predates the digital era.

Most people do not realize that cryptography is a foundational element to our modern society. At it’s heart cryptography is about access to data, and controlling who can see and use it.

Electrical engineers at Princeton, working with UK manufacturer Element Six, created synthetic diamonds capable of storing and transmitting quantum information, as published in the journal ‘Science’ on Thursday. The research is a major advance for the creation of quantum-encrypted communications.

As the Equifax hack last year showed, there’s a lack of legislation governing what happens to data from a breach. And ultimately, a breach of genetic data is much more serious than most credit breaches. Genetic information is immutable: Vigna points out that it’s possible to change credit card numbers or even addresses, but genetic information cannot be changed. And genetic information is often shared involuntarily. “Even if I don’t use 23andMe, I have cousins who did, so effectively I may be genetically searchable,” says Ram. In one case, an identical twin having her genetic data sequenced created a tricky situation for her sister.

One simple reason is that hackers might want to sell DNA data back for ransom, says Giovanni Vigna, a professor of computer science at UC Santa Barbara and co-founder of cybersecurity company Lastline. Hackers could threaten to revoke access or post the sensitive information online if not given money; one Indiana hospital paid $55,000 to hackers for this very reason. But there are reasons genetic data specifically could be lucrative. “This data could be sold on the down-low or monetized to insurance companies,” Vigna adds. “You can imagine the consequences: One day, I might apply for a long-term loan and get rejected because deep in the corporate system, there is data that I am very likely to get Alzheimer’s and die before I would repay the loan.”

S cientists have created the UK’s first ever “unhackable” fibre network in anticipation of the dawn of quantum computers, a technology that could render current security systems completely useless and leave critical infrastructure, banking and healthcare networks open to hackers.

The network, constructed by researchers from BT, the University of York and the University of Cambridge over the past two years, is secured by the laws of quantum physics which dictate how light and matter behave at a fundamental level. Using this, it is able to block anyone attempting to crack into the fibre link.

This could be a game changer for the healthcare and financial sector, when it is feared existing encryption…

Developers at major technology companies, outraged by the Snowden disclosures, started pushing back. Some, such as those at WhatsApp, which was bought by Facebook a year after the story broke, implemented their own encryption. Others, such as Yahoo’s Alex Stamos, quit rather than support further eavesdropping. (Stamos is now the head of security at Facebook.)

Five years after historic NSA leaks, whistleblower tells the Guardian he has no regrets.

E xperts are suggesting quantum computing may render blockchain obsolete. As the tech giants such as Google and IBM are showing interest in Quantum computing the danger is evident. According to MIT Technology Review, this type of computing can hack the cryptography hash that universally secures the blockchain and in general the internet. This would suggest quantum computers may complete fraudulent transactions and steal coins. With its exponential power, quantum computers threaten blockchain’s future security.

Blockchain consists of encrypted nodes connected on a chain, which currently makes it almost impossible to hack. The order of entries adheres to the blockchain protocol, which makes it counterfeit-resistant.

To successfully hack a blockchain, you would need to alter both the targeted block and all of the blocks connected. Blockchains are synced throughout a peer-to-peer network. In this type of system, there is no central point of failure for hackers to penetrate. For a hacker to have a chance of penetrating the network, they would need to simultaneously alter at least 51% of the blockchain.

Machine-learning technology is growing ever more accessible. Let’s not have a 9/11-style ‘failure of imagination’ about it.

There is a general tendency among counterterrorism analysts to understate rather than hyperbolize terrorists’ technological adaptations. In 2011 and 2012, most believed that the “Arab Spring” revolutions would marginalize jihadist movements. But within four years, jihadists had attracted a record number of foreign fighters to the Syrian battlefield, in part by using the same social media mobilization techniques that protesters had employed to challenge dictators like Zine El Abidine Ben Ali, Hosni Mubarak, and Muammar Qaddafi.

Militant groups later combined easy accessibility to operatives via social media with new advances in encryption to create the “virtual planner” model of terrorism. This model allows online operatives to provide the same offerings that were once the domain of physical networks, including recruitment, coordinating the target and timing of attacks, and even providing technical assistance on topics like bomb-making.

There are certain classes of technology that, by their nature, put those who possess their secrets in danger: Nuclear weapons. Ballistic missiles. Advanced encryption software.

Now, add unmanned aerial vehicles—drones—to that list.

A Palestinian electrical engineer who had published research on drones was assassinated in Malaysia, the Wall Street Journal reported (paywall). A helmeted person on a motorcycle fired 10 shots at 35 year-old Fadi al-Batsh, killing him as he walked to a mosque for morning prayers.

Sometimes sensitive data, like passwords or keys that unlock encrypted communications, are accidentally left open for anybody to see. It’s happened everywhere from the Republican National Committee to Verizon, and as long as information can be public on the internet the trend isn’t going to stop.

But researchers at software infrastructure firm Pivotal have taught AI to locate this accidentally public sensitive information in a surprising way: By looking at the code as if it were a picture. Since modern artificial intelligence is arguably better than humans at identifying minute differences in images, telling the difference between a password and normal code for a computer is just like recognizing a dog from a cat.

The best way to check whether private passwords or sensitive information has been left public today is to use hand-coded rules called “regular expressions.” These rules tell a computer to find any string of characters that meets specific criteria, like length and included characters. But passwords are all different, and this method means that the security engineer has to anticipate every kind of private data they want to guard against.
